74ACT244 Logic ICs Datasheet, Features, Pinout, and Applications

The 74ACT244 is an octal buffer/line driver IC manufactured by Texas Instruments. It is designed for high-speed operation and minimal power consumption, making it ideal for driving capacitive loads or interfacing high-performance logic circuits. Commonly used in computing, telecommunications, and industrial automation, the 74ACT244 delivers robust performance in digital signal processing applications.

Overview of 74ACT244

The 74ACT244 octal buffer and driver are specifically designed to enhance the performance and integration density of 3-state memory address drivers, clock drivers, and bus-oriented receivers and transmitters.

This device is structured as two 4-bit buffers and drivers, each with its independent output-enable (OE) input. When the OE input is set to low, the device transmits non-inverted data from the A inputs to the Y outputs. Conversely, when the OE input is high, the outputs transition to a high-impedance state.

74ACT244 Features

• Operates with a VCC range of 4.5V to 5.5V
• Inputs support voltages up to 5.5V
• Maximum propagation delay (t_pd) of 9.5ns at 5V
• TTL-compatible inputs for seamless integration
• For MIL-PRF-38535-compliant products, all parameters are fully tested unless explicitly noted. For other products, standard production processes may not include full parameter testing.
